TO ALL WHOM IT MAY CONCERN:

Be it known that we, SAMUEL C. FRINK and E. Orrs Fawn, of Indianapolis,county of Marion, and State of Indiana, have invented certain new anduseful Improvements in Machines for Bending Wood; and we hereby declarethe following to be 8 full nnd exact description of the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making part of this specification, in which- Fignrc 4represents the former and the bed-plate of the machine. I

Letters U. 'Utheformcr, P the bed-plate, A-the hack of the part thatbolts to the part B. V V is the projcction forward from the back A tothe former U U, bringing the former opposite the slot 0, thereby placingit in position to receive the spine, as represented at Z, figs. 1 and 2.T.T represent the lugs, cast on the bottom of the bed-plate P in such aposition as to receive the eccentric R, and pin g, sections 3 and 4,asrepresented in figs. 1 and 2 of the drawings, the pin 9 being placedin a perpendicular position under the end of the former, asrepresentedbythe hole s in the bed-platc-P, fig. 4, and also in figs. 1and 2, by the pin 9. In the lugs T T is a hole, w, through which theeccentric R is fastened in its position by means of a bolt, asrepresented by r r, figs. 1 and 2. The holes 1 t t in the back plate Aare to receive the bolts that fastenthe machine to the part B, asrepresented infigs. 1 and 2. The holes 0 e in the. slot 0 receive thebolt that fastens the basc-piece E of the spine in its proper positionon the machine, as represented in figs. 1 and 2.

Figure 5, E represents the base-piece of the spine. F is the slide thatslides backward and forward in slot 0, fig. 4. G represents the slotthrough which the bolt 0 passes, so as to confine the base to thebed-plate I when in a perpendicular position, as represented in fig. 1,and to let it slide backward: and take a. horizontal position, asrepresented in fig. 2. D D are two projections, which catch under theears C of the former when the baseplate is moved forward and wedged inits proper position, as represented in fig. 1 by letters E D C. Hrepresent the two projections that slide on each side of the pin g,thereby forming a base for the shoe N, section '5, to rest upon, andalso leave an opening, r, so that the pin g has a chance to be elevatedby the eccentric R,

thereby taking up the'slack between the double clutch or clamp X W,section 1, and'thc gib end of the handle as represented in fig. 1 by Ii.N the shoe, H the base-projection, g the pin, and R the eccentric, atthe gib end 0f the handle, andby W X on the handle beyond the bend. J Jrepresents the space between the projection D D to receive the handleand shoe N at the gib end h. K represents thcback'piccc or clamp thatholds the steel strap L in its-proper position by means of bolts throughthe wings I I.

Figure 7 represents the back part of base-piece E, with the mortise-I toreceive the tcnon or clamp 31 of the back piece K,'-as represented in'fig. 5. f v

Figure 8 represents the back piece, with the strap L hooked on andsecured in its position by means of the screw M. By securing the strap Lin this position it protects the strap from breaking, and makes it pefectly secure. Section 8givcs a side view of the strap L hooked on tothe back piece K, and secured in its position by screw M. Section 9gives a sectional view of the base-piece E, with the projection D H,-thc mortise I, slot G, shoe N, back piece K, strap L, segment Z Y, andhandle 5, all in proper position. Section 1 represents the double clampX,W -.and dog d. .The dog (I is made of wrought iron, forged round andbent at each end-,as represented by d andff, scction 2. On these ends isplaced the serrated-faced clamp X W, W being pivoted to the opposite endof'thc strap L from that of the base-piece E. The whole, when inposition, is represented by figs. 1, 2, and 8, thctwo clamps X and Wbeing free to work on the prongsffof the dog d. Section 2 forms clampwhen wood' is placed between thcm tlmt holds tighter thcinorc strain thehandle gives in bending, and does not slip after the slack is taken upby means of the pin g, shoe N, andeccentric R, as represented in fig. 1.

Figure 3 represents the base-piece E, the back piece K, strap L, onesegment Y Z, and tho serrated-faced clamp W.- The segment Y Z is made ofbrass ormalleahlc iron, and is made in two pieces Y and Z, with a slotbetween thern'of suilicient depth and breadth to receive the strap Lfreely. The scmicirclep is made as near the strap L aspossiblcand'prescrvcs the circle. This saves the handles from staving up toomuch on the outside, and alsdlrccps the semicircle close to the hack ofthe handle in bending, thereby preventing splitting or breaking ofthewood. The projections S S arcvto act as guides on the edge of theformer U U in bending the semicircle piece. Y is pivoted to the backpiccc Z, which st-ifl'cns it and thcrchyprevents it from breaking saw 2at the thin part of the semicircle 1). Section 'l-represents theconnecting-rod bl tilYll .tll Sl\00 N and clamp a, section ii, after thehandle is bent, as represented in fig; i.

To enable others to use our machine in bending plough-handles or otherwood, wc will proceed to describe the process. D

First, place the spine of segments Y Z ina horizontal position, asrcpresentedby fig. '2. Take the handle and place it in the semicirclesegments with the shoe N atthe base, and then shove the other end downagainst the inclined part 1 2, so that the gib end It is brought tightagainst the shoe Al on the base projection II II; then place the doubleclamp on the handle and throw it back on the top side as for aspossible; next bring the handle, with spine of segments attached, to aperpendicular position, and slide them forward so that the projections DD siide under the cars C; then make it fast by pushing down the wedge l,fig. 1. Next, raise the eccentric R by means ofthe handle t, and theslaclc is taken out of the spine by the elevation of the pin and theholding tight of the double clamp W X. Next :use the handle as a lever,and bend down until it is in the position'as shown in fig. 1. While inthis position hook on the connecting-rod b to the shoe N and to theclamp a, and slide the clamp 41 as far as possible and let go of thehandle. Next -hit the clamp X on the side marlced O with a mallet, whenthe clamp will be loosened. Take off the part X and d, and the strap isloose; then remove the wedge 'Z and slide the spine Y Z back, andretnrn'it to its horizontal position, then take the handle that is bentout. I i i We do not claim the former. What we claim as our invention,and desire to secure by Letters Patent, is-

1. We claim the bed-plate P and former U U, when constructed as setforth.

2. We claim the pin 9, the eccentric R, shoe N, and clamp X d W, whenused for taking up the slack of the spine.

3. We claim the base-piece E, the back plate K, the clamp X (Z W, incombination with the strap L, substantially as described and set forth.

4. We claim the segments Y Z, when constructed as described, incombination with the strap Ii, substantially as set forth. 7

5. We do not claim a strap running outside the handle to be bent, but wedo claim the shoe N and clamp a, in combination with the rod 6,substantially as set forth and described, when need to hold the materialin a bent position. v p
